From a developmental perspective, workgroups adjust and modify the way they function over time. The present study aims to test, at the group level, the moderating role of the group’s life phase in the relationship between workgroup interdependence ties in terms of task, outcome and functions, assessed by social network density and group satisfaction. A sample of 84 teams from various companies participated in this research. The results showed that the group’s development phase determines the way that outcome interdependence density in teams is associated with satisfaction and reveal the existence of differences between the second and fourth development stages. Therefore, the group’s life cycle stage should be considered as a relevant variable in research and intervention with groups in the workplace.  相似文献

This article compares native residents’ opinions and perceptions regarding immigration using a representative survey from a pair of matched North Carolina counties – one that experienced recent growth of its foreign-born population and one that did not. Drawing from several theoretical perspectives, including group threat, contact theory, and symbolic politics, we formulate and empirically evaluate several hypotheses. Results provide limited evidence that competition and threat influence formation of opinions about immigration, with modest support for claims that parents with school-aged children harbor more negative views of immigration than their childless counterparts. Except for residents in precarious economic situations, these negative opinions appear unrelated to the immigrant composition of the community. Claims that the media promotes negative views of immigration receive limited support, but this relationship is unrelated to the volume of local immigration. Finally, sustained contacts with foreign-born residents outside work environments are associated with positive views of immigration, but superficial contacts appear to be conducive to anti-immigration sentiments. Political orientation, educational attainment, and indicators of respondents’ tolerance for diversity explain most of the difference between the two counties in overall support for immigration.  相似文献

The main goal of this article is to provide empirical evidence that alcohol consumption reinforces the occurrence of mental illnesses even at early stages of life. We control probit estimations for unobserved heterogeneity and endogeneity. We have drawn a sample of 73,024 individuals from the Spanish National Survey on Drug Use in the School Population (2000, 2002, 2004). Our results confirm our theoretical hypothesis that alcohol consumption has a negative influence on youth state of health, but the magnitude of this influence is lower once we controlled for unobserved heterogeneity and endogeneity. Gender differences reveal that females are more likely to have been prescribed tranquilizers, and they are also more vulnerable to alcohol consumption than males are. As effective instruments to improve young people well-being, we suggest increasing the price of liquors and a greater parental control in how their children spend their available budget, and more important, in how they feel.  相似文献

The aim of this study was to analyze the use of representational gestures from a multimodal point of view in the transition from one-word to multi-word constructions. Twenty-one Spanish-speaking children were observed longitudinally at 18, 21, 24, and 30 months of age. We analyzed the production of deictic, symbolic, and conventional gestures and their coordination with different verbal elements. Moreover, we explored the relationship between gestural multimodal and unimodal productions and independent measures of language development. Results showed that gesture production remains stable in the period studied. Whereas deictic gestures are frequent and mostly multimodal from the beginning, conventional gestures are rare and mainly unimodal. Symbolic gestures are initially unimodal, but between 24 and 30 months of age, this pattern reverses, with more multimodal symbolic gestures than unimodal. In addition, the frequency of multimodal representational gestures at specific ages seems to be positively related to independent measures of vocabulary and morphosyntax development. By contrast, the production of unimodal representational gestures appears negatively related to these measures. Our results suggest that multimodal representational gestures could have a facilitating role in the process of learning to combine meanings for communicative goals.  相似文献

Solution‐focused therapies have had only short‐term effectiveness for clients with serious problems stemming from abuse who come to our family counselling centre in Auckland, New Zealand. In seeking long‐lasting change, we have begun integrating attachment theory into the family systems therapy we have been practising. The Adult Attachment Interview (George, Kaplan, & Main, 1985) has been incorporated into a case in order to study the effectiveness of integrating attachment and family systems theories. This case illustrates how information gathered about the mother's attachment pattern can help the therapist comprehend the client's response to the present crisis, and clear a path through what can appear to be an overwhelming labyrinth of presenting issues.  相似文献

In this paper we focus on adapting the concept of push – pull factors to forced migration by proposing a “push out – push back” approach that underlines two most crucial elements of forced migrants’ experience. On the one hand, it stresses the reasons for leaving countries of origin or of temporary refuge that are not dependant on the will of people who flew those places, thus the “push out” factors. On the other hand, it represents the refusal of the countries of the Global North to accept forced migrants and their use of various practices, amounting to “push back” factors, to prevent them from entering or leaving their territory if they manage to reach it. These factors can be divided into three groups: passive, active, and symbolic.  相似文献

In this paper, the most general bivariate distribution with lognormal conditionals is fully characterized, using the methodology proposed by [3]. The properties of the new family are studied in detail, including marginal and conditional distributions, regression functions, dependence measures, moments and inequality measures. The new distribution is very broad, and contains as a particular case the classical bivariate lognormal distribution. Several subfamilies are studied and a generalization of the basic model is discussed. Finally, we present an empirical application. We estimate and compare the basic model proposed in the paper with a classical model, using data from the European Community Household Panel in different periods of time.  相似文献

In this conceptual paper, proactive international strategies of small- and medium-sized enterprises (SMEs) in the cluster context are discussed. The majority of cluster SMEs assume passive roles as network participants in the process of internationalisation. However, a smaller fraction adopts proactive strategies to foreign expansion acting as leaders of networks. SMEs as network leaders are embedded in the source clusters and dependent on local networks that provide them with complementary resources. We assert that this mutual dependence between a firm's resources and the development of industrial agglomeration should be reflected in the strategic options that SMEs adopt when going international. This paper contributes by synthesising and evaluating a comprehensive range of SME-strategic options and by proposing the proactive competitive strategies of SMEs in the international arena that are both feasible and effective. The feasibility of adopting a specific strategy means the suitability for this group of companies, considering their characteristics. The evaluation of the effectiveness of each strategy was performed according to the objectives of avoiding lock-in and of protecting and developing the core competencies embedded in cluster networks. We address the research gap in evaluating the outcomes of SME international strategies and in synthesising a comprehensive range of cluster SMEs' strategic options.  相似文献
